    GtkTreeViewColumn: start padding at 0
    
    If we start with a padding of -1 then it can leak out of the size
    allocation request for the column when the treeview is empty.  The
    GtkTreeView will then collect these -1 values and add them together,
    returning -n where 'n' is the number of columns.
    
    This is usually not a problem because treeviews tend to be used with a
    scrollbar and the width of the scrollbar will be added to this number
    bringing it into positive territory again.  On Ubuntu, with overlay
    scrollbars, this is not the case, however.
